What is the significance of passing the session ID with every link in PHP?

Passing the session ID with every link in PHP is significant because it allows the server to identify and associate each request with the correct session data. Without passing the session ID, the server would not be able to maintain the user's session state across different pages or requests. 

<?php
// Start the session
session_start();

// Get the session ID
$session_id = session_id();

// Include the session ID in every link
echo "<a href='page1.php?PHPSESSID=$session_id'>Page 1</a>";
echo "<a href='page2.php?PHPSESSID=$session_id'>Page 2</a>";
?>
